摘要
目的 探讨超声雾化表面麻醉应用于小儿支气管镜检术的可行性。方法 5 0例小儿气管异物 ,随机分为表麻组、静脉全麻醉组各 2 5例 ,分别 2 0 g·L-1利多卡因经超声波雾化仪雾化后吸入 8～ 10min ,完成表面麻醉 ;γ 羟基丁酸钠 80mg·kg-1+氯胺酮 1mg·kg-1完成静脉复合麻醉。结果 表麻组围术期并发症少 ,HR、MAP平稳 ,术毕SpO2 >95 % ,清醒时间 (70 1± 15 3)min ,静麻组并发症较多 ,围术期HR、MAP下降明显 (P <0 0 5 ) ,术毕SpO2 <95 % (P <0 0 5 ) ,清醒时间 (16 8 4± 17 6 )min (P <0 0 1)。结论 超声雾化表面麻醉用于支气管镜检表麻完善 ,围术期MAP、HR稳定 ,并发症少 ,术毕低氧发生率低 ,清醒时间短 ,是该手术较好的一种麻醉选择。
Objective To discuss the possibility of ultrasonic superficial spray anesthesia applied to bronchoscopy in children with intratracheal foreign bodies. Methods 50 cases with intratracheal foreign body were divided into two groups: surface anesthesia group (S group) and intravenous anesthesia group (Ⅰ group). 2% Lidocain by ultrasonic spraying inhalation for 8～10 min and r-OH 80 mg·kg -1+Ketamine 1 mg.kg -1 intravenous injection were adminstered respectively. Results In S group perioperative the MAP and HR were stable, the complications were fewer and the SpO 2 was >95%,the awaking time was shorter (70.1±15.3) min after operation;In I group the MAP and HR were descendent (P<0.05), the complications were more and the SpO 2 was <95% (P<0.05), the awaking time was longer(P<0.01). Conclusion The surface anesthesia is effective.The MAP and HR are stable,the complications are fewer and the awaking time is shorter.
